Hello everyone, I would like to seek your expertise on dealing with analog input on a CPU 314C-2PN/DP. I tried so many things in searching some solution why I can't read or receive a value on my analog input channel 0 using with my simulator 4-20mA. CPU online simulation: When I use direct address (%IW800), the value is always steady in zero. and when I use peripheral address (%IW800:P), value is always steady in 32767. PLCSIM simulation: Analog value is doing fine when I modified value from 0...27648 I checked from the analog card manual for the wiring connection. I tried to apply all from the manual but the same problem. Maybe there is something I miss? attached is the screenshot during simulation with CPU and PLCSIM simulator. Really appreciated for your help. Thanks in advance. keep safe. AttachmentSimulation Screenshot.zip (274 Downloads) |

Hi Duris_I, The default address of the cpu 314c-2pn/2dp integrated analog input is 800...8009. I already changed to 752. I checked my simulator output using multi meter and it doings fine from 4...40mA. attached images for your info. thanks. Autogen AttachmentAI overflow to 32767.zip (330 Downloads) |
